Problem with RadDatePicker in dynamically loaded user control.

I'm having a problem with the RadDatePicker when it is used inside a dynamically loaded user control. Also, the dynamically loaded user control is displayed inside a RadPageView.

The problem is this: I set the initial value for the RadDatePicker in server-side code when the user control is first created. The initial value displays correctly when the page is displayed. However, once a postback occurs the value is "lost" (i.e. the RadDatePicker is blank). If you type in a date or select a date using the calendar then the value is persisted across postbacks. It's only the initial value, set on the server side when the user control is created, that is not persisted across postbacks.

Here is some sample code. First, the user control:

WebUserControl.ascx

    
            <%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <telerik:RadDatePicker ID="RadDatePicker1" runat="server">  
        
            </telerik:RadDatePicker>

WebUserControl.ascx.cs

    
            public partial class WebUserControl : System.Web.UI.UserControl  
        
            {  
        
                public void DisplayInformation()  
        
                {  
        
                    RadDatePicker1.SelectedDate = DateTime.Now.Date;  
        
                }  
        
            }

Default.aspx

    
            <%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <%@ Register src="WebUserControl.ascx" tagname="WebUserControl" tagprefix="uc1" %>

I'm trying to use a radprompt windows, everything work fine but when i clik OK in the radprompt Windows, another radprompt open, if i click ten times, ten radprompt open....

The issue is the same on your online demo.

My users will doesn't want to use their mouse for this kind of validations !

I already try the "mybutton.blur()" method or to set the focus to another element of my "backgroud" page without success.

Thank for your help....

[Solved] Stop RadWindow from closing

In my application, I'm using the onbeforeunload event to check for unsaved changes by the user. This works great for regular forms. I tried the same approach with pages used as RadWindows, and it kind of works. If I change a value on the radwindow and click the "x" to close it without saving, the RadWindow closes and then the prompt to save shows up. Obviously this is too late since the RadWindow is now gone. I thought about trying to use the OnClientClose event on the RadWindow, but the documentation states that it is called after the window is closed. Is there a way to to run some javascript when the "x" on the RadWindow is clicked so that I have a chance to stop it and ask the user to save changes?

Configuring RadAjaxManager Programatically

I'm having a problem doing this (as in no code errors but still get postbacks).

I populate a RadTreeView programatically and when a node is clicked I want Ajax to kick in and change the ContentURL of a RadPane.

Can anyone see what I might be doing wrong in the code below (in green),

    
            protected void PopulateNavSites(RadTreeNode LASitesNode)     
        
                    {     
        
                        LASitesNode.Nodes.Clear();     
        
                        DataSet dsSites = Master.Services.Site.getAllSitesByLaName(Master.User.Username, LASitesNode.Value);     
        
                        if (dsSites.Tables[0] != null)     
        
                        {     
        
                            foreach (DataRow Row in dsSites.Tables[0].Rows)     
        
                            {     
        
                                RadTreeNode Node = new RadTreeNode();     
        
                                Node.Text = Row["siteName"].ToString();     
        
                                Node.Value = Row["siteID"].ToString();     
        
                                Node.Attributes.Add("nodeType", "Site");     
        
                                PopulateNavSiteTools(Node);     
        
                                LASitesNode.Nodes.Add(Node);     
        
                                radAjaxManagerProxy.AjaxSettings.AddAjaxSetting(Node, radPaneContent, Master.radLoadingPanel);     
        
                            }     
        
                        }     
        
                    }

[Solved] Splitter in UserControl

Hi

I am using a radSplitter inside a UserControl
and I have a HTML button within this control which is used to CLOSE a Sliding pane

However the Javascript needs to find the RadSlidingZone inside the UserControl
Is there any way to do this? (I'm not a Javascript expert!)

Normally I would put the Java function after the BODY page element as follows
BUT this produces an compilation error because the Splitter is inside a userControl

<body>
<script type="text/javascript">
function ClosePane_SignIn()
{
var slidingZone = $find("<%= RadSlidingZone1.ClientID %>");
slidingZone.collapsePane("RadSlidingPaneSignIn");
}

Any help appreciated...

Regards

Martin
